Built on Quality.
Run by the Guy Who Does the Work.
Mathieu Gratto leads every project personally from start to finish. Based in Vankleek Hill, serving homeowners across Hawkesbury, L'Orignal, and Eastern Ontario — hardscaping that holds up because it's built right.
Owner-Operated. Always On the Job.
Mathieu Gratto started Gratto Hardscapes to do one thing well: build outdoor spaces that last. He grew up in Vankleek Hill and has been working in hardscaping, excavation, and site prep for years — every project gets the same level of care and attention from start to finish.
When you hire Gratto Hardscapes, you're hiring Mathieu directly. There's no foreman passing instructions down the line — he's on the job, making the calls, and accountable to you when it's done.

Every hardscaping project that fails early fails the same way — bad base prep. Too many contractors rush the excavation, skip the compaction, or use the wrong base material to save time and money. Gratto Hardscapes does not do that. We dig proper, we grade proper, and we lay the right base before a single interlock stone goes down.
This matters because what you're really paying for isn't the stone — it's the years of problem-free use. An interlock patio should last decades without heaving, settling, or cracking. A retaining wall should hold without shifting. A drainage system should actually keep water away from your foundation. That's the standard we hold our work to.
We're a small operation by design. Keeping the team tight means staying involved in every project, catching issues before they become problems, and finishing the work the way it was quoted. We work with premium materials including Techo-Bloc and provide fully itemized quotes — so you know exactly what you're getting before we break ground.
